Balloons are inflatable, flexible bags typically made of latex or foil, often filled with helium or air for decoration or celebration. They come in various shapes, sizes, and colors, adding a festive touch to events like birthdays, weddings, and parties. Balloons can be personalized, filled with confetti, or shaped into creative arrangements. They symbolize joy, happiness, and are commonly used for decorations, balloon releases, and even advertising. While latex balloons are biodegradable, environmental considerations have led to the popularity of alternatives like foil balloons. Overall, balloons continue to be a popular and versatile element in celebrations and events worldwide.
